Decide together, with full confidence The multi-user, multi-market negotiation tool for everyone — not just businesses.
Multiple participants connected simultaneously. Propose clauses, vote, counter-propose, sign or refuse, export the final document as a PDF with stamps and a probative audit log. Secure sessions, complete traceability, sovereign data.
See the outcome: a real 3-party negotiated document
This agreement was negotiated in real time between 3 participants (SODIF, CAPEB, El Palacio) on Digital Synapse Exchange. 4 clauses voted, 3 signatures with company stamps, complete audit log — generated automatically by the module.
Real document generated by the Digital Synapse Exchange Negotiation module — fictitious data for illustration purposes.
How does it work?
A complete flow in 6 steps — from session creation to the final signed document.
The manager creates the session
From their group, the manager launches a session and configures: document type, legal template (business, association, union, co-owners), proposal duration and signature deadline. They distribute the session identifier to participants.
Participants join
Each participant joins the session from their browser with the provided identifier. Once the manager starts the session, no one else can join — latecomers are blocked.
Proposals, votes, counter-proposals
During the allotted time, each participant drafts their clauses. The first clause (FIFO order) goes to a vote. Participants accept, reject or submit a counter-proposal. Only one counter-proposal at a time — negotiation stays orderly. Each action is timestamped in the audit log.
Session closure
The proposal timer expires — pending votes continue. When the manager closes the session, no further votes are possible. The manager enters a review phase: they reorder adopted clauses by drag and drop.
Signature phase
After closure, each participant has the configured deadline (24h, 48h, 7 or 15 days) to sign the document (name, title, location, stamp) or refuse to sign. A countdown displays in real time. The manager tracks progress: signed, refused, pending.
PDF generated with audit annex
Once all responses are received (or the deadline expires), the manager validates the order and generates the PDF. The document includes numbered clauses, signatures with stamps, and a complete probative audit annex: timeline of every event, voter identity, vote results, signatures and refusals. The PDF is automatically distributed to each participant's file space.
The Digital Synapse Exchange Negotiation module produces a document signed by all parties — contract, charter, minutes, agreement, protocol… Here are some examples of what can be negotiated and formalized, without this list being exhaustive.
4 legal templates adapted to your context
The manager chooses the template when launching the session. The preamble, terminology and legal framework of the final document adapt automatically.
Business
Commercial contracts, partnership agreements, specifications. General obligations law preamble, mutual consent of contracting parties.
Association
Charters, bylaws, deliberations. Framework of the law on non-profit associations. Resolutions voted by members.
Union / Collective
Collective agreements, protocols, motions. Principles of fair negotiation and good faith. Provisions agreed by representatives.
Co-owners
General meeting minutes, works resolutions. Framework of co-ownership law. Resolutions adopted by co-owners.
Negotiation at the heart of a complete ecosystem
Digital Synapse Exchange is not a standalone tool — it is a multi-task laboratory. The negotiation session fits into an organized flow: preparation groups upstream, real-time chat and files during the session, gallery and follow-up groups downstream.
The manager can create as many groups as needed around the session — each group has its own chat, files and discussions. The architecture is open: each collective organizes its own ecosystem.
Built for multiple simultaneous participants
Each user sees in real time what the others are doing — no reload, no delay.
Instant synchronization
As soon as a participant proposes a clause or votes, all others see the update immediately via Socket.IO — just like being in a physical room.
Distinct roles
The manager facilitates — they do not vote. Participants propose, vote and sign. Separation of powers guaranteed server-side.
Live response counter
The manager sees in real time how many participants have signed or refused. The PDF is only generated once all responses are received or the deadline has expired.
Any device
Web browser only — no installation required. Each participant connects from their PC, Mac, tablet or mobile. The session works everywhere.
Wherever people decide together
From high school students to co-drafting legislation — if it's collective, it's negotiable.
Citizens and Participatory democracy
Citizens co-draft a petition, vote on amendments or deliberate on a legislative proposal. Every voice counts, every step is traced in the audit log.
Co-owners and Residents' collectives
A co-owners' meeting votes on works. A residents' collective makes decisions on common areas. Everything is documented, transparent, contestable. Co-owners template included.
High schools and Universities
A student union votes on its committee or regulations. A jury deliberates. A faculty council adopts a programme. In minutes, from anywhere.
Unions and Organizations
A union votes on a motion, validates an agreement or mandates its representatives. The legitimacy of each decision is documented in real time. Union/collective template included.
Businesses and Committees
An executive committee negotiates a strategy. A tender is examined collectively. FIFO clauses guarantee process fairness. Business template with commercial preamble.
Families and Close groups
A family votes on an important decision — inheritance, shared project. A group of friends organizes collectively with clear rules and a formal agreement.
Key features
Real-time Socket
All actions (proposal, vote, counter-proposal) are broadcast instantly to all connected participants via Socket.IO.
Guaranteed FIFO order
Clauses are processed in the strict order of submission. No clause can jump ahead of another — total fairness between participants.
Counter-proposals
Only one counter-proposal at a time. The original clause is suspended until a verdict. If rejected, it is automatically reactivated.
1–5 star rating
Beyond simple accept/reject, participants rate clauses from 1 to 5. The approval rate is calculated in real time and displayed to all.
Signatures and stamps
After closure, each participant signs (name, title, location, stamp) or refuses within the allotted time. Images are integrated into the PDF then deleted — native GDPR compliance.
Signature refusal
Each participant may refuse to sign. The refusal is counted as a response. The manager sees in real time: signed, refused, pending.
Probative audit log
Every session event is timestamped and identified: proposals, votes, counter-proposals, signatures, refusals. The audit annex is integrated into the final PDF — documentary probative value.
Configurable signature deadline
The manager chooses the deadline after closure: 24 hours, 48 hours, 7 days or 15 days. A countdown displays for each participant. After the deadline, non-respondents are counted.
PDF automatically distributed
The final document is generated once and copied to each participant's file space. No need to send by email — each person retrieves their own copy.
Facilitator manager
The manager facilitates but does not vote — separation of powers guaranteed server-side. They reorder clauses and validate the final PDF once all responses are received.
Latecomer blocking
Once the session has started, no new participant can join. Quorum integrity is preserved from start to finish.
Sovereign data and GDPR
Your negotiations stay on your Digital Synapse Exchange server. Signature stamps are never stored in the database — temporary file only, purged after generation.
Secure and sovereign negotiation
The confidentiality of your negotiations is not optional. Digital Synapse Exchange is designed so that your data never leaves your control.
Only authenticated group members can participate. Server-side verification on every request — no access via direct URL. Latecomers blocked after session start.
Every proposal, vote, counter-proposal, signature and refusal is timestamped with author identification. The complete annex is integrated into the PDF — constituting an autonomous documentary piece in case of dispute.
Signature images pass through a temporary folder, are integrated into the PDF, then deleted immediately. No trace in the database.
Any attached document is analyzed by the FEFCS engine before processing — purely structural detection, zero false positives.
Your next multi-user decision deserves better than a message thread.
